The structure of the tool is reasonably designed. By setting a hammer rod at one end of the pull rod, when disassembling the hinge shaft, only a thrust needs to be manually given to the hammer, and the inertial force of the hammer can be used to impact the limit handle, thereby generating a pulling force on the pull rod and the connecting sleeve to remove the hinge shaft to be disassembled, which can effectively improve the disassembly efficiency of the hinge shaft.

[0004] To solve the above technical problem, the technical scheme adopted by the utility model is: a coal shearer hinge shaft disassembly tool, characterized in that: it includes a pull rod and a hammer rod connected to one end of the pull rod. The pull rod and the hammer rod are perpendicular to each other. A support seat and a connecting sleeve are installed at the end of the pull rod far from the hammer rod. The connecting sleeve is located between the support seat and the hammer rod. The connecting sleeve is used to connect with the hinge shaft to be disassembled. The support seat and the connecting sleeve are respectively pinned to the pull rod through a pin shaft. A hammer is slidably installed on the hammer rod, and a limit handle for limiting the hammer is provided at the end of the hammer rod far from the pull rod.

[0005] The above-mentioned coal shearer hinge shaft disassembly tool is characterized in that: the hammer rod is threadedly connected to the pull rod.

[0010] The utility model has the following advantages compared with the prior art:

[0011] 1. By arranging a hammer rod at one end of the pull rod in the utility model, when disassembling the hinge shaft, the staff connects the connecting sleeve with the hinge shaft to be disassembled, and pushes the hammer along the hammer rod from the end close to the pull rod to the end far from the pull rod with force. The hammer uses a large inertial force to impact the limit handle, and then generates an outward pulling force on the hinge shaft to be disassembled, so as to remove the hinge shaft to be disassembled, which can effectively improve the disassembly efficiency of the hinge shaft to be disassembled.

[0012] 2. In the utility model, the support seat and the connecting sleeve are installed on the pull rod through the pin shaft, so that both the support seat and the connecting sleeve can swing to a certain extent, and thus it can be avoided that the hinge shaft to be disassembled is damaged by the lateral force during the disassembly process.

[0013] In summary, the structure of the utility model is reasonably designed. By arranging a hammer rod at one end of the pull rod, when disassembling the hinge shaft, only a manual thrust needs to be given to the hammer, and the inertial force of the hammer can be used to impact the limit handle, and then a pulling force is generated on the pull rod and the connecting sleeve to remove the hinge shaft to be disassembled, which can effectively improve the disassembly efficiency of the hinge shaft.

[0023] As Figures 1 to 3 shown, the utility model includes a pull rod 1 and a swing hammer rod 5 connected to one end of the pull rod 1. The pull rod 1 and the swing hammer rod 5 are perpendicular to each other. A support seat 2 and a connecting sleeve 3 are installed at the end of the pull rod 1 far from the swing hammer rod 5. The connecting sleeve 3 is located between the support seat 2 and the swing hammer rod 5. The connecting sleeve 3 is used to connect with the hinge shaft 9 to be disassembled. The support seat 2 and the connecting sleeve 3 are respectively pinned to the pull rod 1 through a pin shaft 4. A swing hammer 7 is slidably installed on the swing hammer rod 5. A limit handle 6 for limiting the swing hammer 7 is arranged at the end of the swing hammer rod 5 far from the pull rod 1.

[0024] During actual use, by arranging the swing hammer rod 5 at one end of the pull rod 1, when disassembling the hinge shaft, the staff connects the connecting sleeve 3 with the hinge shaft 9 to be disassembled, and pushes the swing hammer 7 along the swing hammer rod 5 from the end close to the pull rod 1 to the end far from the pull rod 1 with force. The swing hammer 7 impacts the limit handle 6 with a large inertial force, and then generates an outward pulling force on the hinge shaft 9 to be disassembled, so as to remove the hinge shaft 9 to be disassembled, which can effectively improve the disassembly efficiency of the hinge shaft 9 to be disassembled.

[0025] It should be noted that the support seat 2 and the connecting sleeve 3 are installed on the pull rod 1 through the pin shaft 4, so that both the support seat 2 and the connecting sleeve 3 can swing to a certain extent, thereby avoiding damage to the hinge shaft 9 to be disassembled due to lateral force during the disassembly process.

[0026] During specific implementation, by arranging the support seat 2 at one end of the connecting sleeve 3, when the swing hammer 7 impacts the limit handle 6 with a large inertial force, it is convenient to tighten against the connection part between the support seat 2 and the hinge shaft, and then disassemble the hinge shaft 9.

[0027] In this embodiment, the swing hammer rod 5 is threadedly connected to the pull rod 1. An internal thread hole for the threaded connection of the swing hammer rod 5 is arranged at the end of the pull rod 1 far from the support seat 2. An external thread matching the internal thread hole is arranged at the end of the swing hammer rod 5 far from the limit handle 6.

[0028] As Figure 2 and Figure 3As shown in the figure, in this embodiment, an installation groove 8 for installing the support seat 2 and the connecting sleeve 3 is provided at one end of the pull rod 1 away from the swing hammer rod 5. One end of the support seat 2 is provided with a first ear plate 2-1, and one end of the connecting sleeve 3 is provided with a second ear plate 3-1. The first ear plate 2-1 and the second ear plate 3-1 are respectively inserted into the installation groove 8 through a pin shaft 4.

[0029] During actual use, the installation groove 8 penetrates through one end of the pull rod 1 away from the swing hammer rod 5, and the installation groove 8 penetrates through two sides of the pull rod 1 perpendicular to the axial direction of the swing hammer rod 5.

[0030] It should be noted that the setting of the installation groove 8 makes one end of the pull rod 1 away from the swing hammer rod 5 U-shaped.

[0031] In this embodiment, the connecting sleeve 3 is threadedly connected to the hinge shaft 9 to be disassembled.

[0032] During actual use, an internal thread is provided in the connecting sleeve 3, and an external thread is provided at one end of the hinge shaft 9 to be disassembled.

[0033] In this embodiment, the support seat 2 and the connecting sleeve 3 are located on the front side of one end of the pull rod 1, and the swing hammer rod 5 is located on the rear side of the other end of the pull rod 1.

[0034] In this embodiment, the pin shaft 4 is perpendicular to both the pull rod 1 and the swing hammer rod 5.

[0035] During actual use, when disassembling the hinge shaft 9 to be disassembled, the staff first threadedly connects the connecting sleeve 3 to the hinge shaft 9 to be disassembled, places the support seat 2 at the hinge connection part on one side of the connecting sleeve 3, then connects the support seat 2 and the connecting sleeve 3 to the pull rod 1 respectively through two pin shafts 4, then slews the swing hammer 7 on the swing hammer rod 5, and threadedly assembles one end of the swing hammer rod 5 with the pull rod 1;

[0036] The staff pushes the swing hammer 7 along the swing hammer rod 5 from the end close to the pull rod 1 towards the end away from the pull rod 1 with force. The swing hammer 7 impacts the limit handle 6 by using a large inertial force, so that the swing hammer rod 5 pulls the pull rod 1, and the pull rod 1 generates an outward pulling force on the hinge shaft 9 to be disassembled through the connecting sleeve 3, and the hinge shaft 9 to be disassembled is removed.

[0037] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the present invention.
